The objective of any cropping system is efficient utilisation of all resources such as land, water and solar radiation, maintaining stability in production and obtaining higher net returns. The efficiency is measured by the quantity of produce obtained per unit resource used in a given time.

Abstract

The groundwater targeting in hard rock aquifer systems is complex, because of the heterogeneity of the aquifer systems. The ground water mobility and stability in such aquifer systems varies because of the lithology, folded structures, fracture density, geomorphology, slope etc., These occur in various permutations and combinations and control the overall water holding and conducting capacity in different parts of the aquifer systems. Hence, one needs to analyse all the data so as to understand and bring out precise spatial models on the groundwater probability in hard rock aquifer systems. In the present study, the authors have carried out GIS based appraisals to understand the relation between the lithology and groundwater movement in hard rock aquifer systems of parts of Central Tamil Nadu covering 1300 sq.km. In the said study, GIS images were generated on the maxima zones of various aquifer parameters such as water level, width of aquifer depletion, transmissivity, permeability, specific capacity, storage co-efficient, optimum yield and recovery rate. These were overlaid with the lithology GIS image. Such an analysis has shown that, in general, the fissile hornblende biotite gneiss appears to have some control over the groundwater systems.

About 60 per cent of total arable land (142 million ha) in India is rain-fed, characterized by low productivity, low income, low employment with high incidence of poverty and a bulk of fragile and marginal land. Watershed development program is, therefore, considered as an effective tool for addressing many of these problems and recognized as a potential engine for agricultural growth and development in fragile and marginal rain-fed areas. The Government of India has accorded high priority to the holistic and sustainable development of rain-fed areas through the integrated watershed development program since the 7th Five Year Plan (1985-90) and since then a number of watershed programs have been specifically launched in the rain-fed areas with the sole objective to improve the livelihood of poor rural households in a sustainable manner.

Water is indispensable for human, animal and plant life. It is a major component of all organisms some of which contain more than 90% of water. Water is a constituent of protoplasm. It maintains turgidity of cells which is essential for stomatal opening, expansion of cells and for different physiological processes. Water is also required for translocation of nutrients and dissipation of heat.

16.1 Irrigation

Irrigation is generally defined as the artificial application of water to soil for the purpose of supplying the moisture essential for plant growth.

However, a broader and more inclusive definition of the term irrigation is the application of water to the soil for any number of the following six purposes —

1. To add water to soil to supply the moisture essential for plant growth.
2. To provide crop insurance against short duration drought.
3. To cool the soil and atmosphere, thereby making more favourable environment for crop growth.
4. To wash out or dilute salts in the soil.

The conservation of soil and water is very essential for sustainable production, environment preservation and balanced ecosystem. Fifty percent of total geographical area (329 m ha) of our country needs soil and water conservation measures. About 5334 million tonnes of soil is lost annually along with 10 million tonnes of fertilizer and other essential nutrients and organic carbon. Loss of nutrients is almost equal to their total production in India. In India about 70% of the cultivated area falls under the category of dryland conservation measures for soil and water and efficient utilization of these resources is needed in these areas. The fact that rainfed agriculture supports 44% of India’s human population and contributes 90 percent of coarse cereals and pulses, 80 percent of oil seeds and 65 percent of cotton and growing realization that further gains in productivity of crops and live stock will emanate from rainfed regions, leave no room for complacency in this regard.

In these areas, rainfall frequently occurs with high intensity that produces higher runoff due to non adoption of soil and water conservation (SWC) measures and poor permeability of the soil. As a result crop grown during rainy season often suffer from moisture stress due to inadequate moisture storage in the soil profile. Secondly soil erosion problems such as sheet, rill and even gully erosion are common in the region.

It has been reported that the black soils of peninsular region of India, under cultivated fallow gives runoff of about 23.4 percent of rainfall and results in a soil loss of 8.94 t ha^-1 at 1.0 percent slope (Verma et al., 1990). They further reported that the rate of siltation reduced by 83 percent within a span of five years due to adoption of agronomic measure of SWC. These studies clearly showed that soil erosion and runoff are the major factors causing land degradation in the region that needs appropriate SWC measures so that crop productivity could be maintained.

PGPR have shown potentiality against pests and diseases oc curring on crop plants. Wilt and collar rot diseases are caused by soilborne pathogens viz., Fusarium oxysporum fsp. lycopersici (FOL) and Sclerotium rolfsii respectively in vegetables. An attempt was made to manage the diseases with PGPR microbes and 142 PGPR strains were isolated from different vegetable crops. Among them two isolates viz., Bacillus amyloliquefaciens (BA1) and B. subtilis (BS2) were found highly effective in controlling the diseases.  Apart from the disease control, the isolates BA1 and BS2 also registered enhanced crop growth and yield in cowpea under field conditions. Species level identification of BA1 and BS2 was done through PCR amplification and sequencing of 16s rRNA. Both BA1 and BS2 clustered with Bacillus amyloliquefaciens and B. subtilis respectively.

Moisture deficit causing shortfalls in crop production is the characteristic feature of dryland agriculture. Other adverse factors viz., decline in soil fertility together with play of biotic stresses add to the complexities of dryland crop production. Added to the proven agronomic management to combat the problem of drought in dryland agriculture, there is the need to tailoring of suitable crop varieties which can yield reasonably well under conditions of moisture deficit (Varshney et al., 2021). In this context, the appropriate developmental rhythm along with the combination of the constellation of characters of the crop plant matching with the rainfall and the soil moisture availability patterns of the zone are the important considerations together with stability of yield (Hanson and Nelsen, 1980). This task being a complex one, the problem should be approached through multidisciplinary strategy that should buffer the genetic and breeding efforts.

Introduction

One of the most common concerns in irrigated agriculture is regarding water quality or salinity. Out of the ground water surveyed in different Indian States, as much as 84% is rated either saline or alkaline (Minhas 1996). Salinity management is very important for using saline water in irrigation safely. This requires an understanding of how salts affect soil as well as plants, of how hydrogeologic processes affect salt accumulation, and also of how cropping and irrigation activities affect soil and water salinity.

The objectives of management practices for getting optimal crop production with saline irrigation water include the prevention of salt build-up in soil which limit the productivity of soils and the control of salt balances in the soil-water system, as well as minimising the damaging effects of salinity on crop growth (Meiri and Plaut 1985). Amongst the various soil, water, and crop management options available, there is usually no single way to achieve safe use of saline water in irrigation but many different approaches and practices can be combined into satisfactory irrigation systems using saline water. The appropriate combination depends upon edaphic, hydrogeologic, climatic factors as well as social and economic condition of the farmer. Several practices interact with each other, and should be considered in an integrated manner, along with climatic and human factors. Because of the climate, the basic principles of saline water management need some adaptation, e.g. providing for a leaching requirement is not appropriate when the growing season for post-monsoon winter crops starts with a surface-leached soil profile, because it would increase the salt load. High salinities during the initial stages of growth are particularly harmful. Recommendations for effective management of irrigation water salinity depend upon local soil properties, climate, and water quality; options of crops and rotations; and irrigation and farm management capabilities

El Nino is the name given to the occasional development of warm ocean surface waters along the coast of Ecuador and Peru. When this warming occurs the usual upwelling of cold, nutrient rich deep ocean water is significantly reduced. El Nino normally occurs around Christmas and lasts usually for a few weeks to a few months. Sometimes an extremely warm event can develop that lasts for much longer time periods. In the 1990s, strong El Ninos developed in 1991 and lasted until 1995, and from fall 1997 to spring 1998.

El Nino means ‘The Little One’ or ‘Christ Child’ in Spanish. It was originally recognized by fisherman of the coast of South America as the appearance of usually warm water in the Pacific Ocean, occurring near the beginning of the year i.e. around Christmas. That is why the name is used. El Nino, the periodic warming of Pacific Ocean waters that affects the weather worldwide. C. Fred and T. Andrus of the University of Georgia studied the ancient fish bones from refuse left about 6000 years ago by ancient peoples in Peru and found that ocean catfish lived in water that averaged 60 to 70 warmer than now and that there was little variation in temperature. He concluded that if El Nino was occurring at the modern rate, once every two to seven years, then the bones from the fish would have reflected the temperature variation.

18.1 Determination of Electrical Conductivity of Soil Solution

The conductivity or more precisely the specific conductance of a soil at a given soil-water ratio is the reciprocal of the specific resistance offered by the solution at 25ºC between the electrodes of 1 sq cm cross section kept 1 cm apart. Thus, the electrical conductivity of any solution depends on the amount of soluble salt present in it. Knowledge on the extent of salinity is important for management of saline soil including the choice of the crop suitable for that soil. Soluble salt content in saturation extract is more reliable index of salinity level than in soil: water ratio of 1: 2 or 1: 2.5, because it simulates the extent of salinity experienced by crop in field moisture condition.

Salinity class of soil is based on the electrical conductivity (EC) of saturation extract at 25ºC. However, EC of water extract from 1:2 soil-water suspension can be transformed into the EC of saturation extract following the formula (except for soil containing gypsum).

Pure water is a poor conductor of electricity. Water may carry electricity fairly well when it contains electrolytes such as Acids, bases and salts. Electrolytes in the solution dissociates with cations and anions and pass on electrical conductivity. Hence, more electrolytes concentration in water, more its electrical conductance. The following ions are crucial for adding conductivity to water.
i) Cations: Mg 2+,Ca2+, Na+ and K+
ii) Anions: Cl-, S4
-, CO3
-, HCO3
-and NO3

In the International System of units (SI) the reciprocal of ohm is the Siemens (S) and conductivity is reported as millisiemens per meter (mS/m). 1 mS/m = 10 µS/cm = 10 µmhos/cm and 1 µS/cm = 1 µmhos/cm Principle
The quantity and kind of ions present in a solution affect conductivity, which is a numerical representation of a water sample’s capacity to conduct electricity. Since the majority of dissolved inorganic compounds in water are ionised, they add to conductance. The definition of conductance G is the reciprocal of resistance R.

Principle

Different ions migrate at different speed dictated by their size and by the amount of charges they carry. As a result, different ions can be separated from each other by electrophoresis. The magnitude of the electric force F exerted on the charged particle when subjected to electrophoresis is product of the charge q of the particle and the electric field E generated between the two electrodes.

Electrophoresis is an important separation technique for the charged molecules. Biologically important molecules, such as amino acids, peptides, proteins nucleotides, nucleic acids which carry electrical charge as they possess certain ionizable functional groups may be separated and identified from a mixture with the help of this technique. Some compounds that are non-polar in nature and do not possess any charge may be transformed to charge carrying derivatives. Thus, phosphate derivatives of carbohydrates may be separated and characterized utilizing electrophoretic techniques.

Introduction 
Building on our extensive exploration of how individual weather parameters intricately influence every facet of crop life and the diverse methodologies employed to evaluate these responses, we now embark on a journey into the mathematical heart of crop science. This chapter, Elementary Crop Growth Models,” will introduce you to the foundational concepts and simpler mathematical frameworks used to quantify, simulate, and ultimately predict how crops grow under varying environmental conditions. In the upcoming sections, we’ll delve into the fundamental building blocks of crop modeling. You’ll discover how these elementary models simplify the complex biological processes occurring within a plant to create manageable, yet insightful, representations. Unlike highly detailed mechanistic models, which require vast amounts of data and computational power, elementary models focus on capturing the most essential relationships between environmental drivers (like solar radiation, temperature, and water) and key aspects of crop growth, such as biomass accumulation or phenological progression. These simpler models serve as a crucial stepping stone. They allow us to grasp core principles of crop-weather interaction in a quantifiable way, providing practical tools for initial assessments, quick predictions, and conceptual understanding, without getting lost in the overwhelming complexity of every single physiological pathway. By understanding these foundational models, you’ll gain a clearer perspective on how agricultural scientists begin to predict the future performance of our food crops, even as the climate around them continues to evolve

The plant can absorb more than sixty elements as revealed from the plant tissue analysis, still a few elements is considered essential for the growth and nutrition of the plants. The deficiency of any one of the essential elements can stop completing the life cycle of the plants which is reflected on the yield of the crop. The growth of the plant which is expressed in terms of dry weight, length ,diameter etc. are interlinked with the plant available nutrients of soils.

3.1 Essential Nutrients

The essential elements are those elements which are required for growth and nutrition of the plants. There are 17 elements known to be essential nutrients for plants. The essential elements are classified as micro and macronutrients depending upon the requirement of the crop. Among the naturally occurring elements, eighteen elements are considered essential to plants. These are: C, H, O, N, P, K, Ca, Mg, S, Fe, Mn, Zn, Cu, B, Mo, Cl, Ni, Co. The elements which are found in different sources are required to be in available forms (Table 3.1) for growth and nutrition of the plants.

5.1 Introduction

In recent decades, human induced changes in climate of the earth have the focus of scientific and social attention. The most imminent of this is the increased concentration of greenhouse gases (GHGs) namely, carbon dioxide (CO₂), methane (CH₄) and nitrous oxide (N₂O) in the atmosphere. The concentration of CO₂, CH₄ and N₂O have increased markedly by 30%, 145% and 15%, respectively as a result of human activity since 1750, the era of Industrial Revolutions (IPCC, 2007). Between 1750 and 2005, the concentration of CO₂, CH₄ and N₂O in the atmosphere has increased from 280 to 379 ppm, 715 to 1774 ppb and from 270 to 319 ppb, respectively (IPCC, 2007). However, there was a steep increase during the recent years i.e. 70% increase of GHGs between 1970 and 2004.

8.1 Design of Canal Embankments

 There are two aspects of canal embankment design.

 (i) The general requirement, such as free board, dowel, service/inspection road, drainage of banks etc. The aspect of free board is discussed in Para

8.2 to 8.3 and that of service/ inspection road in Para

 8.4 and drainage of banks in Para 8.5 in this chapter.

 (ii) Safe design of embankment i.e. Hydraulic and structural requirement.

It includes stability of inner and outer slopes, Structural safe design of inner cut slopes in deep cuttings in different types of soils/rocks of varying nature and ground water conditions. Stability of slopes may include drainage, so as to prevent rock falls/debris in canal. For outer slopes in embankment (filling sections) hydraulic gradient/pharetic line, toe drains etc, similar to the earthen dams, on different types of soil/rock foundation with respect to varying ground water level conditions are important.

The canal embankments in filling may even fail through its foundations by sloughing or liquefactions. All these aspects of canal embankments are discussed in this chapter in Para 8.4 to 8.9.

Technology Scouting and Innovations in Technology Incubation
Technology scouting and innovations in technology incubation have a symbiotic relationship, fuelling each other for the benefit of budding startups and the broader technology ecosystem. Let’s dive deeper into their individual roles and how they interact:
Technology Scouting
Technology Scouting is the process of discovering, analyzing and evaluating new or existing technologies that will help them with their innovation process. In simple terms, it is a process for companies to find the necessary technology outside the company.
Hunting for promising technologies: Scouts actively search for emerging technologies, patents, research advancements, and market trends across various sectors.
Evaluating potential and fit: They assess the technical feasibility, market potential, and compatibility with the needs of incubators and their supported startups.
Connecting innovators and ventures: Scouts bridge the gap between technology creators (researchers, inventors, startups) and potential users (incubators, established companies).
Fuelling innovation pipelines: Technology scouting helps incubators access a wider range of technologies and ideas, enriching their portfolio and diversifying the innovations supported.

Introduction
In the paradigm of development, the Government of India generated a Central Sector Scheme for the people associated with agriculture – a sector contributing to 18.2 per cent of the nation’s GDP, titled “Formation and Promotion of 10,000 Farmer Produce Organizations (FPOs)” with major focus on upheaval of farming community. With well-defined strategy and committed resources the Scheme is set-out to formulate 10,000 new FPOs in the country with budgetary provision of Rs 6865 crore. At the core of formation of each FPO, that are to be developed in produce clusters, wherein agricultural and horticultural produces are grown / cultivated for leveraging economies of scale and improving market access for members. “One District-One Product” cluster to promote specialization and better processing, marketing, branding & export. Under this Central Sector Scheme with funding from Government of India, Formation & Promotion of FPOs are to be done through the Implementing Agencies (IAs). Presently 09 Implementing Agencies (IAs) have been finalized for formation and promotion of FPOs viz. Small Farmers Agri-Business Consortium (SFAC), National Cooperative Development Corporation (NCDC), National Bank for Agriculture and Rural Development (NABARD), National Agricultural Cooperative Marketing Federation of India (NAFED), North Eastern Regional Agricultural Marketing Corporation Limited (NERAMAC), Tamil Nadu-Small Farmers Agri-Business Consortium (TN-SFAC), Small Farmers Agri-Business Consortium Haryana (SFACH), Watershed Development Department (WDD)- Karnataka, and Foundation for Development of Rural Value Chains (FDRVC)- Ministry of Rural Development (MoRD). The Implementing Agencies (IAs) engage Cluster Based Business Organizations (CBBOs) to aggregate, register & provide professional handholding support to each FPO for a period of 5 years. CBBOs have been empanelled & engaged by IAs. CBBOs operate as an end-to-end knowledge for all issues related to FPO promotion. During 2020-21, a total of 2200 FPO produce clusters were allocated for formation of FPOs, which also include specialized FPO produce clusters such as 100 FPOs for Organic, 100 FPOs for Oil seeds, etc. Of these, 369 FPOs are targeted for 115 aspirational districts in the country. Additionally, NAFED would form the specialized FPOs which should necessarily be forwardly linked to the market, agri-value chain, etc. NAFED will provide market and value chain linkages to the FPOs formed by other Implementing Agencies. NAFED has formed & registered 05 Honey FPOs during current year in Uttar Pradesh, Madhya Pradesh, Rajasthan, Bihar and West Bengal. FPOs are earmarked to provide financial assistance upto Rs 18.00 lakh per FPO for a period of 03 years. In addition to this, provision has been made for matching equity grant upto Rs. 2,000 per farmer member of FPO with a limit of Rs. 15.00 lakh per FPO and a credit guarantee facility upto Rs. 2 crore of project loan per FPO from eligible lending institution to ensure institutional credit accessibility to FPOs.

1. Introduction
In recent decades, environmental contamination has emerged as a seriousthreat to our modern society. The relentless growth of urbanization andindustrialization leads to the ever-increasing production of hazardouschemicals. Safe disposal of these hazardous materials is crucial, as releasingthem into an already strained environment has severe consequences. Theexponential rise in human activity is directly related to the alarming risein local and global pollution levels, which severely disturbs the balance ofecosystems. Industrial activities, in particular, are a major source of highlyhazardous chemicals such as dyes, pigments, and aromatic compounds,which pose a serious threat to the environment. In India, the textile industry, amajor force driving the country’s economic growth, also ranks asthsecondlargestpolluter. The printing, finishing, and dyeing processes used in textileproduction generate significant waste (Dubey et al., 2018). Dyes, a majorsource of pollution in this industry, are syntheticand complex in structure. Thiscomplexity makes them poorly soluble in water, hindering biodegradation andposing a long-term environmental concern. The global textile industry utilizesa wide range of dyes, with estimates indicating over 100,000 commerciallyavailable options. The worldwide production of these dyes is estimated to be700,000 tons per year (Al-Tohamy et al., 2020). However, dye contaminationis a major challenge in this industry. Studies indicate that during synthesisand dyeing processes, a significant portion, ranging from 10% to 15% of thetotal dyestuffs used ends up released into global water bodies (Leal et al.,2020). A significant portion of textile dyes, ranging from 2% to 20%, aredirectly released into water reservoirs through wastewater effluents. This is

Training plays a vital role in enhancing the capabilities of individuals to perform their roles effectively. In the context of leadership development, training aims to equip potential leaders with the necessary skills, knowledge, and attitudes to excel in their roles. This paper examines the objectives of leadership training and the methods by which these objectives can be achieved.

Meaning of Training

The term ‘training’ refers to a structured process designed to improve an individual’s ability to fulfill their responsibilities. It involves imparting knowledge, developing skills, and shaping attitudes to enhance professional competence. For potential leaders identified through various selection methods, training serves as a means to cultivate essential leadership traits that may be lacking initially.

Introduction Agricultural sector is the pillar of the Indian economy. It provides employment to around half of the workforce of the country and contributes around 18 per cent to the gross value added of the country. Small and marginal landholdings, constituting less than 2 hectares, make up a significant 85 percent of India’s farming community (Joshi, 2022). These small farmers encounter various challenges, including farm-specific and household transaction costs that limit their participation in input and product markets. With changing food preferences driven by income and population growth, there’s a growing need for small-farm commercialization to meet the rising demand for diversified, higher-quality diets (Chakraborty, 2020). To address the constraints faced by small farms, aggregation models have emerged as institutional interventions.

Introduction Terms total development of rural areas with the purpose of increasing the quality of life for rural people is referred to as rural development. It is a broad anddiverse concept that encourages the expansion of agricultural and allied activities, communities, cottage industries and crafts, community services and facilities, and total human resources in rural areas. As a strategy, rural development is the result of interactions between many physical, technological, economic, and societal elements. Its purpose is to improve the economic and social well-being of a particular rural demographic group. Rural development is a multifaceted concept that covers various aspects of development in order to improve rural people’s quality of life (Ilbery, 2008). Agriculture, village industries, crafts, community services, and rural human resource development all fall under this category.

Abstract

Gender Budgeting was first introduced in 1985 and is being implemented globally by more than 50 countries to ensure gender equality goals. India took initial steps towards analysing the gender gap through “Towards Equality” a Report of the Committee on the Status of Women by the Government of India in 1974. Gender based resource allocation in the country was seen from 1990s onwards in the Eighth Five Year Plan (1992-97) when for the first time gender perspective and the need to ensure definite flow of funds from general developmental sectors to women was emphasised upon. Women constitute 49% of human population in India so it is extremely important that the untapped gender potential is recognized, reorganised and utilized efficiently & effectively to attain a leading position in S&T sector. India has expanded her R&D base immensely since the turn of the 21^st century. Consequently there has been 10 times enhancement in enrolment of women in S&T disciplines in institutions of higher education since 1989-90. Department of Science and Technology has taken many steps in recent past to strengthen the ecosystem to empower women in S&T domain, particularly by enabling over 4000 of them who had a break in career, primarily due to familial responsibilities, to make a dignified comeback. Several Role Models, who have shown their mettle and made a mark in the chosen field, are emerging and engaging & encouraging the young, Gen Next girls.

A case study was made in Geemarahalli village, Nanjangud taluk of Mysore district during 2009-10 to know the performance of women SHG involved in cultivation of tuberose.  JSS Krishi Vigyan Kendra which was started during 1994 analyzed the problems of farmwomen that they were unorganized in doing the field operations and were almost isolated in nature.  KVK initiated in formation of women SHGs in many villages and one of such village is Geemarahalli.  Ms. Rajamma was selected as group leader of the group and her contact with KVK was started since 1996 and still continued.  She is an innovative woman despite being illiterate.  Earlier she was doing tailoring and wire bag making. Later, she developed an interest to take up farming. She formed a Self Help Group called Triveni in her village which consists of 15 farmwomen.  In the beginning, they were involved in farm operations as contract workers.  During 2007-08, this group had come in contact with KVK and were imparted the training programmes on vermicompost production, horticulture nursery management, production of biological agents etc.  Later, the group came forward to learn the cultivation aspects of tuberose which has got good market at Mysore city.  To start this venture, the possession of land was the constraint for them and they overcome it by taking a 10 gunta land on lease basis. They were imparted series of trainings on tuberose cultivation at KVK. 

Abstract

Beekeeping or modern apiculture is the art and science of rearing, breeding and managing honey bee colonies in artificial hives for economic benefits. Beekeeping has evolved into a farming enterprise that involves the use of sophisticated and artificial techniques to keep honey bees for bee products. It is estimated that beekeeping is practiced in about four lakh villages and provide employment to over 3.50 lakh persons. The existing vegetation wealth of India can sustain six million bee colonies which would produce six lakh metric tonnes of honey besides generating part time employment to more than 15 million rural and tribal households. Rural women have long working hours, spent on food production and processing and/or waged labour, in addition to family care and domestic duties. However, beekeeping represents one opportunity for income generation which need not be time consuming and can fit in well with women’s priority activities. Population, female (% of total) in India was reported at 48.18 % in 2017, according to the World Bank collection of development indicators. Rural population (% of total population) was reported at 66.46 % (83.3 crore) in 2017 as compared to urban population (37.7 crore). There are fewer women than men beekeepers, but women beekeepers are found throughout the developing countries of every continent. Participation of rural women and youth in beekeeping activities provides a unique opportunity to improve rural livelihood and hence poverty reduction. Beekeeping as an agro-industry presents tremendous potential and requires attention on part of planners, policy makers, development agencies and researchers on the one hand and wider publicity about the commercial and scientific uses of beekeeping products on the other. In order to increase income accrued from beekeeping activities, promoting and support of training on processing of secondary bee products to women and youth beekeepers are important. Stakeholder’s involvement in promoting and support beekeeping awareness campaigns is crucial to enhance the contribution of the sector for livelihood improvement and environmental conservation.

Abstract

Women in India constitute a larger proportion of total unemployed population and hence it is imperative to find out the entrepreneurial problems faced by them. A study was conducted with the objectives to ascertain the financial, marketing and production problems faced by women in their enterprises and assessment of their health status and work place facilities. Boutiques, beauty parlors, embroidery units, fruit and vegetable preservation units and artificial jewelry making were the enterprises selected for study. The results of the study revealed that women faced problems in areas like finance, marketing, health, work place and production. Some recommendations of the study are a) Women entrepreneurs should keep abreast of knowledge about new techniques, financial institutions, training institutions and marketing linkages. b) Information about site or location, physical facilities, transportation etc. must be collected prior to selection of area for development of an enterprise. c) Self help mutually aided groups must be formulated for overcoming common entrepreneurial problems. d) Women should shift to the non-traditional sectors of entrepreneurship in order to earn more.

Youth in India had been at the forefront of the nation’s struggle for freedom and development. There are over one billion youth in the world today. Eighty five per cent of these youth live in the developing world and around 50 per cent of the population with in developing countries live in rural areas. According to 2001 census, more than 40 per cent of the total population is between the age group of 15 to 35 which is considered as “youth” by the Government of India. Out of which, 73 per cent resides in the rural areas (Anonymous 2001). Unfortunately rural youth of today are counted among the most disadvantaged groups of society. Because of rapid population growth, widespread unemployment inadequate health, poor education, migration, lower family income and lacking adequate opportunity at farm level had led the rural youth in continued stress of self esteem and self confidence. Youth empowerment is an attitudinal, structural and cultural process whereby young people gain the ability, authority and agency to make decisions and implement change in their own lives and the lives of other people. Youth are the present and the future of humanity.

Abstract

Women play a pivotal role in agriculture, in addition to the traditional role of nourishing progeny as mother and attending to the day to day needs of the home as housewife. Women also add to the family income as wage earners. While comprising half of humanity, contributing to two thirds of the world’s work hours, a woman earns only one third of the total income and owns less than one tenth of the world’s resources.  In a country like India which is the home  for over 400 million women, the economic status of women is in pathetic condition and they have always been discriminated against men in human resource development with  utter disregard to their actual and potential contribution to the national progress in general and agricultural progress in particular. The largest sector of India’s economy, agriculture, contributes to 37 percent of the Gross National Product (GNP) and accounts for 60 percent of the employment.

Abstract

Women emancipation, women liberation, women awareness, women upliftment, women empowerment, gender equity etc. are the buzz words our media cashes on. But the question remains: What has made us all to talk about her in 21st century? Unfortunate, but true that women, constituting one half of the total world population, have been treated as second class citizens and denied even the basic rights. Men have dominated her by neglecting her talent, capabilities and potential. Many measures were undertaken by the Government for the betterment of the women such as the creation of National Commission for Women, Parliamentary Committee on Empowerment of Women, Gender Budgeting besides creating many disciplines in various institutions/Universities for women studies and passing several   pro women laws to protect her rights. But this is not enough. What is needed is the freedom from disability of any kind lying in the minds of various sections of the society. A woman need not be pitied but given the due she deserves.

Introduction

Fruits are important sources of vitamins, carbohydrates, fiber and sugar. A large variety of fruits are grown in India, of which mango, banana, citrus, guava, grape, pineapple and apple are the major ones. In India, grapes occupies fifth position amongst fruit crops with a production of 16.77 million tonnes from an area of 0.64 million ha (FAO, 2009). The total grape export from India during the year 2007-08 was 96,723 tonnes worth Rs 317.84 crores. (APEDA, 2009). Grape is an excellent source of many nutrients and phytochemicals, able to contribute to a healthy diet. Grapefruit is a good source of vitamin C and pectin fiber. The major varieties of grapes grown in India are Thomson seedless, Sonaka, Anab-e-Shahi, Perlette, Banglore blue, Pusa seedless, Beauty seedless etc. (NRCG, 2009). Red grapes are grown in large quantities, especially for wine and juice production. Grapes are used for making jam, juice, jelly, vinegar, wine, grape seed extracts, raisins, grape seed oil and some kinds of candy.

Abstract

Variously defined endophytes are highly diverse in plants in natural ecosystems, and most of them are symbiotic with of them are Asymptomatic presence of endophytic fungi in internal tissues on healthy host plants are able to play vital roles in physiology and biochemical processes. As a result of this interaction endophyte produces chemical substances having various applications. This chapter provides a brief review of certain grass and non-grass endophytes capable to extend beneficial impacts on host plants to sustain the unfavourable conditions of abiotic stresses. However, biotic stresses are also a matter of great concern, where endophytes can play important roles in combating the unfavourable situation. Endophytic fungi used in bio-control and other agriculture related sectors are also  highlighted in this review. Endophytic fungi producing volatile organic compounds reported from all over the world and their various applications find place in this article which has opened new frontiers of bioprospecting of endophytic fungi.

Microbes that live inside plant tissues without causing disease are termed as endophytes. Endophytes have been found in all parts of plant viz., seeds, roots, stems, leaves, fruits etc. Within these organs, there is evidence of endophytes living in apoplastic intercellular space within parenchyma tissues and xylem vessel apoplast. Endophytic bacteria have been isolated from both monocotyledonous and dicotyledonous plants, ranging from woody tree species to herbaceous crop plants. Further, a single plant may be a host for several different bacterial species. They are consistently present in the root, stem, leaf, fruit and tuber tissues of a wide range of agricultural, horticultural and forest species. All plants in nature harbor a diverse community of endophytic bacteria which can positively affect host plant growth.

The potential of endophytic bacteria to fix nitrogen, promote plant growth and suppress plant diseases has renewed interest in such associations. It is advantageous to have the endophytic plant growth promoting organisms safely inside the plant, which could supply substantial amounts of nitrogen and other nutrients, growth hormones and other beneficial effects to the crop plants without the interference of the rhizosphere soil environment. Furthermore, plant growth promotion is often greater when it is induced by endophytes rather than by rhizosphere bacteria.

Abstract

In its natural environment, a plant faces various types of stressors. In fact, stress in moderation is a welcome event in plants. Only when it is in excess, would it compromise the productivity of plants. Beyond a threshold, stress (biotic and abiotic) has a detrimental effect on plant growth causing extensive yield losses in crop plants worldwide. Plants being sessile, have evolved a complex set of mechanisms to perceive the changes in the environment. Plants respond to minimize the potential damage due to stress while simultaneously preserving resources vital for their growth and development. The chapter presents an overview of various types of biotic and abiotic factors that act as plant stressors and the mechanisms by which plants respond to these stresses. The chapter concludes with a perspective on how the plant’s innate stress response machinery can be exploited for achieving higher tolerance to stress in crop plants.

Introduction

The basic needs of life are food, clothing and shelter. In the 21^st century a fourth need added to mankind is energy. According to the laws of physics, energy is defined as capacity to do work. Energy, economics and the environment are mutually dependent. Also, there is very close relationship between agriculture and energy. The level and pattern of energy use in agricultural production system depends on variety of agronomic and socio-economic factors. Energy use in agriculture encouraged maximization of yields from limited available arable land, minimization of labour intensive operations and improving standard of living. Efficient and effective energy use in agriculture is one of the conditions for sustainable agricultural production, since it provides financial savings.

7.1. What is Energy Conservation?

In order to protect resources for future use and to lessen environmental degradation, energy conservation refers to actions performed to limit energy use.

.2. What is Energy Efficiency?

The definition of energy efficiency is the use of less energy to carry out a task or achieve a goal. Homes, buildings, and manufacturing facilities that use less energy to manufacture things require less energy to heat, cool, and operate appliances and electronics.

13.1 Introduction

At a national level, the agricultural sector is one of the major potential users of energy in the Indian context. Further, it is often highly dependent on the supply of electricity and fuel in order to function properly. The term “agriculture” refers to all on-farm activities required for farming, raising animals, and associated activities associated with farmers, growers, and entrepreneurs. Fuels such as petroleum and electricity are primarily used for the operation of pump sets and other operations. In the future, this may result in problems with supply and price. Moreover, India has relatively small reserves of crude oil and will eventually be forced to import more crude oil to make up for the lack of reserves. In order to save energy and money on the farm, farmers must identify opportunities for energy conservation on the farm in order to maximize energy efficiency. 

Introduction

Energy Consumption is considered as the energy used to do any task in any kind of a simple domestic building to a complicated manufacturing industry. For instance, in a household, energy is consumed in the form of electricity used to run an Air Conditioner to make a room cool, gas used to cook a dish etc. In a car industry, energy is consumed in the form of electricity to manufacture a car part. In the transport sector, petrol or diesel or gasoline is used as a run a car or bike or other vehicles.

2.1 Time and Energy Requirements of Work
The time and energy requirements of work can vary significantly depending on several factors related to the nature of the work, the worker’s capabilities and motivation, and the workplace environment. Let’s explore each aspect:
1. Nature of the Work
Complexity: work that requires high levels of skill, expertise, and problemsolving will generally demand more time and energy.
Physical demands: jobs that involve manual labor or physically strenuous activities can be more energy-intensive.
Cognitive demands: intellectual or creative work can be mentally taxing, requiring concentration and focus for extended periods.
2. Worker Factors
Physical health: a worker’s overall health and fitness level can impact how much time and energy they can dedicate to their job.
Skill set and experience: experienced workers might complete tasks more efficiently, reducing time requirements.
Motivation: highly motivated individuals tend to invest more energy and time into their work.
Work-life balance: if a worker is dealing with excessive stress or personal issues, it can affect their ability to concentration and perform optimally.
3. Workplace Factors
Work environment: a comfortable, well-designed workspace can contribute to increased productivity and reduced fatigue.
Technology and tools: access to advanced tools and technology can streamline tasks and save time and energy.
Support and collaboration: a positive work culture and supportive colleagues can enhance job satisfaction and productivity.
Workload and deadlines: unrealistic workloads and tight deadlines can lead to stress and exhaustion.

The rapid growth of Large Language Models has produced remarkable advances in artificial intelligence but has also increased computational requirements, energy consumption and environmental impact. This chapter examines the relationship between large-scale AI development, energy efficiency and sustainable computing. Modern AI models may contain billions or even trillions of parameters and require extensive datasets, powerful accelerators and energy-intensive data-centre infrastructure for training and inference. The chapter investigates the environmental consequences associated with model development, including energy consumption, carbon emissions, cooling requirements and resource utilization. It examines model-level optimization techniques such as pruning, quantization and knowledge distillation as methods for reducing computational demands. System-level approaches, including specialized hardware accelerators, energy-efficient data centres, improved cooling systems, renewable energy and intelligent workload scheduling, are also considered. The distinction between energy efficiency and broader sustainability is emphasized, with attention to metrics such as energy per inference, total energy consumption, carbon emissions and hardware lifecycle impacts. The chapter further highlights the importance of transparent sustainability reporting, green computing and governance policies. Sustainable AI development requires balancing model performance and innovation with responsible resource use and long-term environmental objectives

5.1. Introduction

The energy equivalent can be considered to be an alternate energy unit, precisely related to units such as the joule, calorie, or Btu. In energy talks, many units are employed. They are divided into two categories: (a) basic units and (b) source-based units.
